Real time volumetric imaging of gas-solids fluidized beds using ECVT
ECVT has been widely used for real time volumetric imaging of gas-liquid, gas-solid fluidized beds, and gas-liquid-solid three-phase systems. Research has been extensively conducted at the Department of Chemical and Biomoleculer Engineering at the Ohio State University.

The ECVT system is applicable for medical diagnosis, process optimization, and various industrial processes including:
- Drying
- Wetting
- Solids handling
- Pneumatic conveyor
- Oil pipelines
- Fluidization system
- Mixing processes
- Powder processing
ECVT imaging of drying process of solid particles
Our ECVT system is adjustable for low contrast permittivity and high contrast permittivity materials. The sensors can detect low permittivity ratios (relative permittivity value of 2) such as air-plastic beads systems. High permittivity ratios (relative permittivity value of 80) are also detected, such as air-water systems.
ECVT also enables the use of arbitrary shapes of sensor geometries for different applications including pipe bend, T-junction, cone, cube flat plane, and their combinations.
